If we have internal codes in pptok.c, we may have false matches for
them as tokens, plus, there is no reason for them to exist there. Go
back to putting NULL in those slots.

Simplify the handling of conditionals; remove the PPC_* types.
Automate the generation of case-sensitive versus case-insensitive
directives, and make it so the bulk of the code doesn't have to worry
about it.

Clean up some perl warnings, some of which were legitimate (apparently
undef doesn't actually take a list of arguments, a common enough
mistake that it is mentioned in the man page!, and a list of variables
after "my" can be cantankerous), and some of which were nuisance but
were easy enough to clean up.
Maybe this can resolve the problems with very old version of Perl?

For almost everything we should use "nctype.h". Right now we don't
have a nasm_toupper() to use <ctype.h> for things that need toupper().

The 2-operand form was inherently unsafe. Use the 3-operand form
instead, which guarantees that arbitrary filenames are supported.
This also means we can remove a few instances of sysopen() which was
used for exactly this reason, however, at least in theory sysopen()
isn't portable.

Make the source code easier to understand and keep track of by
organizing it into subdirectories depending on the function.
